[0054] ​The application further provides that the sorting assembly 5 comprises two inclined plates 52 arranged in the support 1, the two inclined plates 52 are oppositely arranged, and the sorting assembly 5 further comprises two conveying rollers 51 arranged below the inclined plates 52, the bolts falling on the two conveying rollers 51 are conveyed to the receiving assembly by the conveying rollers 51. Specifically, the two conveying rollers 51 are driven by transmission shafts 531, the transmission shafts 531 are externally sleeved with belts, the number of the transmission shafts 531 is two, the two transmission shafts 531 are fixedly connected with the two conveying rollers 51 respectively, and the conveying belts 53 are in transmission connection with the belt pulleys on the output shaft of the motor, so that the two transmission shafts 531 can be driven to rotate when the motor rotates, and the two conveying rollers 51 can be driven to move, and as shown in the figure, the two conveying rollers 51 are provided with spiral grooves, so that the arranged bolts can be effectively conveyed to the receiving assembly when the two conveying rollers 51 rotate. Figure 4

[0055] In the embodiment, the inside of the support 1 is further fixedly provided with a discharging plate 54, the bolts fall on the inclined plates 52 through the discharging plate 54 after being separated from the limiting plate 2, and finally fall between the two conveying rollers 51. Specifically, the two conveying rollers 51 further have a gap, the gap can make the threaded column of the bolt pass in and hinder the head of the bolt, the size of the gap is smaller than the maximum size of the bolt head and larger than the diameter of the threaded column, so that the bolt can be carried and conveyed.

[0056] In the embodiment, the two conveying rollers 51 are arranged in an inclined mode, and the inclined direction is towards the carrying assembly, and the horizontal plane where one end of the two conveying rollers 51 close to the receiving assembly is lower than the horizontal plane where the other end is. Figure 10 As shown in the figure, the horizontal plane where one end of the two conveying rollers 51 close to the receiving assembly is lower than the horizontal plane where the other end is, and the position is more convenient for conveying the bolts.

[0057] In the embodiment, the upper end surface of the blocking strip 8 has an inclined surface, and the inclined surface and the limiting plate 2 form an upper feeding space 801, when the upper feeding space 801 passes through the lowermost end of the discharging space 101, the blocking strip 8 passes through the fixedly arranged fixed baffle 7, carries the bolts in the discharging space 101, and continuously conveys upwards, and the discharging space 101 and the limiting plate 2 form a discharging hole 1011, the bolts in the discharging space 101 gradually fall into the discharging hole 1011, and finally are carried and moved upwards by the blocking strip 8.

[0058] In the embodiment, the two ends of each blocking strip 8 are fixedly provided with connecting plates 81, and the connecting plates 81 are rotatably arranged on the transmission chain 6, and each blocking strip 8 moves through the conveying of the transmission chain 6. ​

[0059] In the further preferred embodiment of the present application, the plurality of synchronous operation assemblies are arranged corresponding to the plurality of blocking strips 8, and the limiting plate 2 is further provided with a release hole 201, when the synchronous operation assembly moves to the position of the release hole 201, the synchronous operation assembly is automatically opened to make the bolt in the feeding space 801 contact the limiting plate 2.

[0060] In the further embodiment of the present application, the synchronous operation assembly comprises a blocking plate 9 slidingly arranged on the connecting plate 81, and the two ends of the blocking plate 9 are further provided with sliding columns 91, one end of the sliding column 91 is located in the connecting plate 81 and is provided with a limiting guide column 93, and the limiting guide column 93 is located in the limiting groove 811 arranged in the connecting plate 81; the limiting guide column 93 is located in the limiting groove 811 and can only move in the limiting groove 811, during the movement of the sliding column 91 relative to the blocking plate 9, the limiting guide column 93 moves along the limiting groove 811 to drive the sliding column 91 to slide into the blocking strip 8.

[0061] The release hole 201 corresponds to the position of the sliding column 91, when the sliding column 91 moves to the release groove, the sliding column 91 is passively lifted under the tension of the elastic member 92 and drives the blocking plate 9 to synchronously move upwards, so that the bolt in the feeding space 801 contacts the limiting plate 2.

[0062] The synchronous operation assembly can cooperate with the blocking strip 8 to avoid the bolt directly contacting the limiting plate 2 when transporting the bolt upwards, thereby greatly reducing the self-wear of the bolt when moving upwards, ensuring the quality of the bolt and reducing the wear of the limiting plate 2, and when the synchronous operation assembly moves to the release hole 201, it can be passively released, so that the upward movement of the blocking plate 9 can make the bolt smoothly fall onto the discharging plate 54 after separating from the limiting plate 2, that is, not only can the wear between the two be reduced, but also the discharging can be smoothly and passively, the functionality of the device is improved as a whole, that is, the smooth discharging is realized, the above structure can not only greatly reduce the friction between the bolt and the limiting plate 2, avoid the contact and friction between the two, but also can make the blocking plate 9 passively restore through the cooperation between the synchronous operation assembly and the limiting plate 2, facilitate the transportation of the bolt next time, and improve the linkage and use effect of the device as a whole.

[0063] In use, this invention first places a number of bolts into the feeding space 101, then starts the machine. The motor driving the transmission chain 6 and the motor driving the conveying pipe move simultaneously. The transmission chain 6, driven by the sprocket, then drives the partition bar 8. When the partition bar 8 reaches the lowermost feeding hole 1011 of the feeding space 101, it can carry the bolts inside the feeding hole 1011 and move upwards. At this time, the partition plate 9, limited by the sliding column 91 and the limiting plate 2, is within the feeding space 801. Figure 14 As shown in the diagram, during the continuous upward movement, the sliding column 91 gradually moves into the release hole 201, thereby causing the sliding column 91 to move upward under the tension of the elastic element 92, and driving the baffle plate 9 to move upward synchronously, so that the bolt in the feeding space 801 no longer contacts the baffle plate 9, and the bolt contacts the limiting plate 2 at this time. Finally, after continuous upward movement, the baffle bar 8 gradually detaches from the limiting plate 2, and finally causes the bolt to gradually fall onto the unloading plate 54, and finally onto the inclined plate 52, and then pass between the two conveying rollers 51, the head of the bolt... Located between two conveyor rollers 51, which are also inclined, the bolts gradually align and move onto the receiving assembly during the movement of the conveyor rollers 51. Then, through the bearing space 301 between the two feeding plates 3, they gradually slide down to the workstation to be used. At the same time, when the synchronous running assembly transports the bolts again and passes under the limiting plate 2, the sliding column 91 contacts the bottom of the limiting plate 2 and is blocked. As the connecting plate 81 gradually moves upward, the sliding column 91 is still blocked by the limiting plate 2, thereby allowing the bolts to slide down the plate. The moving column 91 and the connecting plate 81 undergo relative displacement, causing the sliding column 91 to gradually move towards the partition bar 8. As the partition bar 8 moves upward, it drives the partition plate 9 to move upward synchronously. Simultaneously, the elastic element 92 (an elastic element 92 is a tension spring in the prior art, one end of which is fixedly connected to the connecting plate 81, and the other end is fixedly connected to the sliding column 91) is pulled open, and the limiting guide column 93 gradually moves along the upper limit groove 811. Due to the action of the limiting groove 811, the sliding column 91 gradually moves towards the connecting plate 81. The internal movement eventually disengages from the barrier of the limiting plate 2. When it is completely disengaged from the barrier of the limiting plate 2, the sliding column 91 is no longer blocked and moves synchronously with the connecting plate 81. At this time, the barrier plate 9 moves to the bottom and forms a feeding space 801 with the inclined surface on the barrier bar 8. Then, during the synchronous upward movement, the sliding column 91 rolls along the limiting plate 2 and carries the bolts in the feeding space 101 during the synchronous upward movement. Then it continues to move upward and carries the bolts in sequence according to the above principle and conveys them to the sorting component 5 in sequence.

[0064] The foregoing merely illustrates some exemplary embodiments of the application, and it will be appreciated that those skilled in the art will be able to devise various modifications without departing from the spirit and scope of the application. The appended drawings and description are illustrative only, and are not intended to be limiting.
